As you have probably noticed, new versions have arrived of Ubuntu, Xubuntu and other derivatives. One of the most exciting new features has received far less publicity than it deserves - the ability to 'install' it onto your USB flash drive with just a few clicks. The advantages are obvious: just plug your flash drive into a computer and run your favourite operating system. What's more, everything you do - installing applications, saving documents, editing preferences - will be saved to your flash drive and will be available to you every time you run it! The best news is that it's astoundingly easy: all it takes is a few clicks.
